Here is keyboard matrix of TOSHIBA SATELLITE C660 keyboard:
Interface for connect TOSHIBA SATELLITE keyboard to ZX. (this is only example of very easy interface and keyboard is readable on defferent port than ZX keyboard = it's not replacement)
I plan make adapter for connect laptop keyboards as ZX keyboard replacement (need CPLD with decoder)
Laptop keyboards contain only membrane similar as ZX keyboard. Matrix connection is different, but with decoder we can convert all to ZX compatible matrix. Laptop keyboard is ideal for custom case for new zx clone(s).
Very big part of PC keyboards and Laptop keyboards use bad membrane matrix and is impossible use some combinations of three keys. At 90% on your keyboard not work game controll QWERT or 12345 or 67890 or QAOPM or QAOPspace or CURSOR+0. But membrane in TOSHIBA SATELLITE keyboards use very good connection and are usable all keys combinations used in ZX games. Price on Ebay is not so big (lower than price of new ZX membrane)
